All I get are terrible headachesOverall Experience:
I bought my Teeter Hang up about 5-6 years ago. I have seen the Roger guy on HSN. I purchased it due to disc degeneration past back fusion with a rod that did not work. I use the Teeter less and less after all these years and I still get terrible headaches. I can't hang backwards for more than 2-3 minutes. The blood just rushes to my head and I get terrible pain in my head.
I thought I would get use to it with longer use but as I get older headaches get worse. It does stretch my back but I have to stay pretty leveled. It can also give you high blood pressure. I have also read risks of stroke. Roger never talks about this.
I guess it would be good for people who have no other health problems except for their back.
Bottom Line: No, I would not recommend this to a friend
